The couple has been together for about two decades, meeting when Stefani's band No Doubt toured with Rossdale's band Bush in 1995, People.com reported. They dated for six years before they wed in 2002.

"While the two of us have come to the mutual decision that we will no longer be partners in marriage, we remain partners in parenthood and are committed to jointly raising our three sons in a happy and healthy environment," the couple told the website in a statement.
